TON GS.

My present invention has reference to a tongs for gripping cables, wiresor the like, and the object of the invention is the provision of adevice for this purpose, characteristic of simplicity in constructionand thorough ei'iiciency in operation.

A. further object of the invention is the provision of a tongs for thispurpose which will effectively grip a cable or similar article '0between the jaws thereof, and wherein the increase in pull upon thehandle of the device will effectively increase the grip of the jaws uponthe cable.

The accompanying drawings illustrate a satisfactory embodiment of theimprovement and wherein Figure 1 is a side elevation of my improvedtongs.

Figure 2 is an edge view thereof with no parts in section.

Figure 3 is a fragmentary elevation with the aw portions of theimprovement in section.

liigure a is a sectional view on the line lit of Figure As disclosed bythe drawings my improved tongs comprises a pair of curved arms 1 and 2respectively. These arms have their outer portions crossed, arranged inlap ping connection and pivotally connected, as at 8. The arm 2, at theportions thereof extending beyond the pivot 23, is flattened and has itsinner face concaved. longitudi .nally, as at 4, to provide the jaw. Theportion of the arm 1, extending beyond the pivot is likewise flattenedand has its inner face widened from its inner edge and the outer edge ofthe said widened portion is rounded, inwardly to provide a second jawThe inner end of the jaw is flared or curved mmvardly, as at 6, and theopposite end of the said jaw is substantially straight. Thus 1925.Serial No. 41,843.

the active face of the jaw 5 is centrally bowed inwardly.

The arms 1 and 2 are rounded away from each other and have their outerends formed with eyes 6 for links 7, and passing through the said linksT there is a ring member 8 that provides the handle of the tongs.

The arms 1 and are swung so that their jaws 4 and 5 are moved away fromeach other to permit of the arrangement of a cable, wire or the liketherebetween. A pull is then exerted upon the handle ring 8, whichswings the arms 1 and 2 toward each other, likewise bringing the jaws land 5 t0- ward each other, so that the cable 9 is effectively grippedbetween the jaws. Be

cause of the particular and peculiar forma tion of the jaws 4 and 5 thegreater the pull on the handle 8, in an upward direct-ion, the tighterthe cable will be gripped between the aws.

Having described the invention, I claim A cable tongs comprisingoppositely disposed arms which cross each other and are pivoted togetheradjacent one end thereof, the end of one arm adjacent the pivot beingflattened by having its inner face conca-ved longitudinally to form ajaw, the other arm being likewise flattened adjacent the pivot pointsand having its inner face widened from its inner edge and the outeredge'of the widened portion rounded inwardly to form a second jaw, theinner end of the second jaw being curved outwardly and the oppo site endof the second jaw being substantially straight and the said second jawbeing bowed inwardly with one end curved inopposed relation, and meansattached to the arms opposite the jaws whereby to move said jaws towardand away from each other.

In testimony whereof I aflix my signature.

JOHN HOWARD KRUM.
